Abstract

556,241. Spring suspensions. STRAUSSLER, N. March 14, 1942, No. 3387. [Class 108 (ii)] [Also in Group XXXI] Comprises a spring suspension means for the rollers or driving or idler sprockets wherein the bearing housing d or s of each sprocket or roller is connected by a pair of parallel links h, i to the vehicle body a and the inner end of each link has one end of a torsion bar spring n secured thereto co-axially with the pivotal axis of the link, the other end of the torsion bar being secured at p to the vehicle body. In the construction shown applied to the bearing housing d of a non-driven sprocket the links h, i have bosses k pivoted in brackets m and one end of each torsion bar is splined at n in the corresponding boss. The other end of each torsion bar passes through and is splined to an anchor plate 1 and has upper and lower studs p the ends of which bear against the face of the bracket, so that by adjusting these studs separately the plate can be turned about the axis of the torsion bar and the initial stress in the latter can be varied. The bearing housing s of a driving sprocket is similarly mounted and the sprocket shaft w is driven through gearing u, v and a shaft y provided with universal joints z, x. The rollers bearing on the track may be similarly mounted, but in this case the torsion bars will extend transversely of the vehicle.
